Plessy v. Ferguson, a legal case in which the United States Supreme Court, by a seven-to-one majority advanced the contentious "separate but equal" theory for determining the constitutionality of racial segregation statutes on May 18, 1896.
Plessy v. Ferguson was the first important case to consider the interpretation of the Fourteenth Amendment's (1868) equal-protection provision, which prevents states from refusing "equal protection of the laws" to anybody within their borders.
The majority ruling, which did not use the slogan "separate but equal," gave constitutional approval to statutes that segregated the public services and facilities available to African Americans and Whites on the basis of race.
